From Page 14 of the Season 3 Rulebook (bold added for emphasis):
Target Number Tests
Many actions a model may make are resolved using a target number (TN) test.
Models use their attributes and apply all relevant modifiers to gather a number of six-sided dice (D6), in order to generate a dice-pool.
Each relevant action confers a base number of dice to the dice-pool; action specific modifiers are then applied. All other applicable modifiers are then applied from Character Traits, Plays and other in-game effects and abilities. This will provide a total dice-pool for the action.
The target number needed is shown as a number in brackets.
When making a TN test, each individual die rolled in the dice-pool that equals or exceeds the target number generates a successful hit. Any die that rolls less than the target number is unsuccessful.
Some actions will have modifiers that affect the number of successful hits after the dice-pool has been rolled.
A TN test is successful if it generates at least [1] net-hit. In many TN tests, additional hits improve the overall result.
The character play Clone used by Snakeskin and Vitriol reads:
Clone 2/ S - The next time this model is hit by an enemy Attack or Character Play that targets this model, except while making an Advance, the Attack or Character Play is ignored. This model then makes a [2”] Dodge.
The trait Glutenous Mass reads:
the pulse suffer [3] DMG and the poison condition. Gluttonous Mass The first time each turn this model is hit by an enemy Attack or Character Play that targets this model, except while making an Advance, the Attack or Character Play is ignored.
Some character plays like Piledriver, Tutelage and Midas Touch and some Plot cards like Who Are Ya? and Vengeance can grant additional net hits to an attack.
What does it mean for a model to be hit by an attack? Does it mean that the attack is successful? Does it mean that some dice in the target number test generated a successful hit? Based on previous rulings that Clone and Glutenous Mass affect character plays triggered off of playbooks, I'd guess it's the former.
Suppose an attack against a model benefiting from Clone or Glutenous Mass generates no hits; the TN test is not successful. A token is removed, added net hits to the attack. Is the attack successful now? Since it wasn't successful when the dice pool was rolled, does the attack 'hit' and trigger Clone or Glutenous Mass? Do character plays that grant net-hits behave differently to tokens that grant net-hits?
